ata format Raw (.csfasta) and processed (.txt) xperimental factors 2 genotypes and food intake in kilocalorie (kcal) from the carbohydrate-rich diet in a diet choice paradigm (see below). xperimental features For 2 d, mice were provided a choice between two diet mixtures containing either 78% fat/22% protein or 78% carbohydrate/22% protein (per cent by energy) and then were euthanatized for col...

The ability of grazing animals to enhance quality of diet by selection is important in production. The study determined the effects of selection on dietary quality of cattle grazing monocultures of smooth bromegrass (Bromus inermis Leyss; SB), switchgrass (Panicum virgatum L.; SG), and big bluestem (Andropogon gerardii Vitman; BB) as influenced by plant maturity. Three ruminally-fistulated stee...

Humans have been argued to be biologically adapted to a cooked diet, but this hypothesis has not been tested at the molecular level. Here, we combine controlled feeding experiments in mice with comparative primate genomics to show that consumption of a cooked diet influences gene expression and that affected genes bear signals of positive selection in the human lineage. Liver gene expression pr...

The present research looked at the ability of gilthead seabream to discriminate between two similar diets differing only in the extent of lipid oxidation. Six groups of 4 fish (254g initial wet weight) were allowed to select by means of self-feeders between two complete diets (34.5% casein + gelatin, 14.8% fish oil + soybean oil, 24.8% dextrin and 25.9% vitamins, minerals, filler and binder) wh...

As with any organ, differences in brain size--after adequate control of allometry--are assumed to be a response to selection. With over 200 species and an astonishing diversity in niche preferences and social organization, Tanganyikan cichlids present an excellent opportunity to study brain evolution. We used phylogenetic comparative analyses of sexed adults from 39 Tanganyikan cichlid species ...

Energy intake and genetic background are major determinants of muscle fat content in most animals, including man. We combined genetic selection and dietary energy supply to study the metabolic pathways involved in genetic and nutritional control of fat deposition in the muscle of rainbow trout (Oncorhynchus mykiss). Two experimental lines of rainbow trout, selected for lean (L) or fat (F) muscl...

objective the aim of the present study was to evaluate the efficacy and tolerability of a modified atkins diet for intractable childhood epilepsy. materials & methods twenty one children with medically intractable epilepsy were enrolled in the study. inclusion criteria were at least four seizures per month and a trial of at least three anticonvulsants without becoming seizure-free. the subjects...
